摘要：

The first-order theory of Donnell is applied to evaluate the natural frequencies of doubly curved cross-ply composite shells. In this paper a meshless method based on multiquadric radial basis functions is used for discretization of equations of motion and boundary conditions. It is shown that natural frequencies obtained by this approach are very accurately determined. (c) 2005 Elsevier Ltd. All rights reserved.
